This is more a solution for bigger turbos that produce more power and need more fuel due to the air they take in.
The stock turbo max out at 450-460hp with added fuel(meth, e85, etc). The plague you're referring too was addressed by BMW and was recalled. If you haven't yet, go to your local dealer and get this issue addressed. Every situation is different, but the first thing they do is upgrade the software. It primps the pump before starting the car at the press of the unlock button. The second thing they do is replace the HPFP with the new part.

This pump vtt is working on should let us get more fuel with upgraded turbos and not need meth as a bandaid.

A guy in Toronto who never laid eyes on the car and who I have never met. Yet the car broke the HP record. If your reasoning is you have no one to tune it cause you live in Kansas, then you don't want it tuned. Good luck

You are right, I have no dedication. I only left my car at HPF for 3.5 YEARS.

Please notice my Screen Name and join date.

I know what you are saying man... But when i come home from deployment, I have to be able to report for duty... not try and find some random guy to PAY... and hope he figures it out. I would send it to SHIV if anyone since its on his tune. But that would require me to send it away again, Which I cannot do.

Are you using a scaler with Cobb?
